Dracen Announces DRP-104 (sirpiglenastat) Presentations at AACR Virtual Annual Meeting
Posters further expand on preclinical immuno-oncology mechanism of action and combination therapy with various checkpoint inhibitors and confirm DRP-104 single agent activity in KEAP1 and STK11 mutant lung tumors and head and neck squamous cell carcinoma
New York, NY, Apr. 5, 2021 /PRNewswire-PRWeb/ -- Dracen Pharmaceuticals, Inc., announced today that three posters profiling its clinical stage glutamine antagonist, DRP-104 (sirpiglenastat), will be presented Saturday, April 10 - Monday, June 21 during the American Association for Cancer Research (AACR) Virtual Annual Meeting.
"As our lead asset DRP-104 (sirpiglenastat) advances in phase I clinical development, our preclinical data continues to confirm its promising profile both as a single agent and in combination therapy," said Robert Wild, Ph.D., chief scientific officer of Dracen Pharmaceuticals. "The data being presented at AACR this year confirm that DRP-104 has significant single agent activity in various tumor types, including KEAP1 and STK11 mutant non-small cell lung cancers (NSCLC), osimertinib resistant NSCLC, as well as PIK3CA/PTEN mutant head and neck squamous cell carcinoma (SCCHN). Additionally, DRP-104 has demonstrated therapeutic synergy with various immune checkpoint inhibitors, including anti-PD-1/PD-L1, anti-CTLA-4 and anti-TIGIT. These data suggest that DRP-104 is a promising therapy for lung cancers and SCCHN and can potentially be combined with several different immune checkpoint inhibitors for improved therapeutic outcome. We are excited about advancing this promising compound in the clinic."

About DRP-104
Our lead glutamine antagonist, DRP -104 (sirpiglenastat), is currently in early-stage clinical development. The mechanisms of action for DRP-104 include: a) direct inhibition of tumor cell addiction to glutamine leading to substantial single agent activity and tumor regression; b) broad metabolic remodeling of the tumor microenvironment leading to enhanced anti-tumor immune activity; and, c) stimulation of T effector, NK and NKT cells and inhibition of immunosuppressive MDSC and macrophage cells, leading to greater long-term durable responses and survival.
